# Determine the volume v0 of each aluminum cylinder

This preview shows page 1 - 3 out of 4 pages.

Determine the volume V0 of each aluminum cylinder; record these values in Table 1 5. Measure the apparent weight, W’, of the submerged cylinder; record the values in Table 1 6. Repeat steps 4 and 5 for the remaining cylinders 7. Calculate the force of buoyancy B, for each cylinder, reporting the value in grams in Table 1 8. Plot B as a function of V0. You should have 3 points (one for each cylinder). Fit the data with a regression line, and pL could be obtained from the slope. 9. Fill the beaker with ethanol and repeat steps 5 through 8. 10. Find the slope of the curve which should be the density of the fluid. Record the density of the fluid. Record the ethanol below and compare it with the accepted value of 0.79 g/cm^3 by calculating the percent difference. Part 2 1. Fill beaker with water 2. Record the ID of an unknown object in Table 2 3. Weigh the unknown object and record the value in Table 2 4. Using figure 1 as a guide, fully submerge the object in water and measure its apparent weight, W’, and its volume Vo. Record the value in Table 2 5. Calculate the density by applying equation 4, record the value in Table 2 6. Calculate the density using the definition of density and record the value in Table 2 7. Identify the substance using the chart 8. Repeat steps 2 through 6 for all three objects.  #### You've reached the end of your free preview.
